Hens in the henhouse

HARRISBURG, Pa. — State Veterinarian Dr. Kevin Brightbill is urging Pennsylvania’s poultry industry, including backyard bird owners, to step up their biosecurity practices as East Asia and Europe report cases of highly pathogenic avian influenza.

“Written biosecurity plans are good, but they are only effective when deliberately acted upon day in and day out by you and every farmhand,” Brightbill said.

Highly pathogenic avian influenza is reported to be circulating in East Asia and Europe, including the countries of Bulgaria, Cambodia, China, Czech Republic, Denmark, Germany, Hungary, Ireland, Japan, Kazakhstan, Laos, Netherlands, Poland, Slovakia, Romania, Russia, South Korea, Taiwan, United Kingdom, Ukraine and Vietnam.

HPAI is known to spread rapidly and be fatal for chickens and turkeys. The last outbreak of HPAI in Pennsylvania, H5N2 in 1983, resulted in the loss of more than 17 million chickens, turkeys and guinea fowl in order to contain and eradicate the disease.

Poultry producers should limit exposure of poultry to wild birds through confinement rearing and other biosecurity measures to reduce the risk of introduction of avian influenza virus. Such practices are key to decreasing the risk of circulating strains of avian influenza from evolving into highly pathogenic forms.

Recent detection by USDA Wildlife Services during routine wild bird surveillance of migratory waterfowl in Washington County detected H4N8 low pathogenic North American wild bird lineage virus in a mallard duck, which confirms avian influenza is circulating in Pennsylvania and producers should be on-guard to protect their flocks.

Biosecurity basics to avoid avian flu for poultry producers include:

• Allow only essential personnel to access your property and your birds. Disinfect any vehicles that enter your farm.

• Don’t lend or borrow equipment from other farms. Bring only cleaned and disinfected items into your bird area.

• Avoid contact with other poultry. If you cannot avoid contact, change clothes and shoes before working with your own birds.

• Wash your hands thoroughly with soap and water before entering your bird area.

• Use footbaths when entering or leaving your bird housing (change disinfectant frequently), or wear disposable boot covers.

• Keep poultry separate from wild birds. Don’t let them share water sources or have access to common areas frequented by wild birds.

• Eliminate standing water on your farm and clean up feed spills to avoid attracting wild birds.

Watch for these signs of avian influenza and immediately report sick or dying birds:

• Sudden increase in bird deaths in your flock.

• Sneezing, gasping for air, coughing and nasal discharge.

• Watery and green diarrhea.

• Lack of energy and poor appetite.

• Drop in egg production or soft- or thin-shelled, misshapen eggs.

• Swelling around the eyes, neck and head.

• Purple discoloration of the wattles, comb and legs.

• Ruffled feathers, listlessness, lethargy.

Poultry producers with sick or dying birds should immediately report them to Pennsylvania’s state veterinarian by calling 717-772-2852 and press option 1.
